Over the last several months I've seen an increasing interest inÂ concrete polishing throughout the industry. Contractors have been processing and polishing concrete for many years, but with polishing's low-maintenance and "green" benefits, its popularity has exploded. Many of the contractors I spokeÂ toÂ or have written aboutÂ lately are involved in concrete polishing and want to learn more, like Beyond Concrete and CSolutions/Middle Georgia Concrete Constructors, or are looking to get into this growing niche. One helpful resource I recently learned about is the Concrete Processing Technical Institute, an educational resource that offers training and accreditation in concrete polishing. Other polishing training resources include Bob Harris's Decorative Concrete Institute and the manufacturers who sell grinding and polishing equipment. You can also learn more about concrete polishing in this overview of concrete processing or thisÂ story about concrete and LEED certification.
